Abstract
The invention belonging to the technical field of mechanical engineering, and in particular relates to a rolling bearing device capable of eliminating a play. The rolling bearing device comprises a bearing inner ring, rolling bodies, a bearing outer ring and a bearing locating sleeve. The bearing locating sleeve is matched with the bearing outer ring, the bearing locating sleeve is provided with an outer wall taper of 1:50, the bearing inner ring is provided with an inner hole taper of 1:12; and two lines of rolling bodies of cylinder bodies or spheres are adopted without arranging a retainer. The invention has the advantages of simple structure and convenient assembly, can eliminate axial and radial plays of a bearing, has the function of automatic alignment and is suitable for bearing a heavy load.
Description
Technical field
The invention belongs to mechanical engineering technical field, be specifically related to a kind of device that can eliminate the rolling bearing play.
Background technique
The play of so-called rolling bearing is that a lasso of bearing is fixed, and another lasso radially or axial maximum activity amount is divided into two types of axial internal clearance and radial internal clearancies.Play during bearing operation is called working gap, and working gap all has a significant impact dynamic performance (noise, vibration and friction), running accuracy, working life (wearing and tearing are with tired) and the bearing capacity of bearing.In general, the bearing working play is big more, and the contact stress of rolling element is big more, bear vibration is strong more, noise is big more, running accuracy is low more, working life is short more.Therefore, reduce or eliminate bearing clearance to reduce the vibration, reduce noise, significantly improve the bearing running accuracy and working life all significant.
Through the literature search of prior art is found, Chinese patent application number is 200720014676.1, and name is called in the patent of clearance-free bearing, has disclosed a kind of clearance-free bearing.The outer shroud of this bearing is made up of two and half outer shrouds, between two and half outer shrouds and the outer retainer elastomer is housed respectively, regulates the radial and axial gap of bearing by elastomer.There is following deficiency in this bearing: the elimination of play realizes by elastomer, both has been unsuitable for bearing for a long time heavy load, also is unfavorable for the maintenance of bearing running accuracy.
Chinese patent application number is 99209791.6, and name is called in the patent of the adjustable play rolling bearing of combined type, discloses a kind of rolling bearing of can regulate play.The outer ring of this bearing is made up of two-part---be with externally threaded outer ring and tapped outer ring, reach the purpose of eliminating play by the adjustment packing ring of regulating between two outer rings, this bearing structure complexity, operation inconvenience and be difficult to realize the continuous adjustment in gap.
At above present situation, be badly in need of a kind of simple structure of development, can bear heavy load, easy to assembly quick, have the self-aligning function and can guarantee the rolling bearing play cancellation element of bearing rotating accuracy.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, provide a kind of simple in structure, easy to assembly, can eliminate the rolling bearing system of the axial and radial internal clearance of bearing.
Rolling bearing system provided by the invention comprises: bearing inner race, rolling element, bearing outer ring, bearing setting sleeve.Wherein, the inwall of described bearing inner race cooperates with bearing shaft, and in the raceway of described rolling element between described bearing inner race and bearing outer ring, described bearing outer ring outer wall and bearing setting sleeve inwall are fixed, and described bearing setting sleeve is by being bolted on the bearing support.
The inwall of described bearing inner race is provided with the tapering of 1:10-1:15.
The outer wall of described bearing setting sleeve is provided with the tapering of 1:45-1:60.
The outer wall of the inwall of described bearing inner race or bearing setting sleeve is the circular cone stage body, and described tapering is meant the poor of circle radius and upper base circle radius of going to the bottom of circular cone stage body, with the ratio of the height of circular cone stage body.
The setting of above-mentioned tapering specifically can rule of thumb be determined in order to eliminate the axial and radial internal clearance of bearing.
Described rolling element adopts cylindrical body or spheroid, and retainer is not set, and rolling element is set to two row (two raceways are promptly arranged), and is covered with along raceway.
The present invention compared with prior art has the following advantages: this device is compared with common rolling bearing, and only set up the bearing setting sleeve and on bearing inner race, be provided with hole taper, so simple structure, easy to assembly; Because structure is provided with rationally, adopt the biserial rolling element and retainer is not set, so good rigidity, be applicable to the occasion of bearing heavy load for a long time; Because bearing setting sleeve and bearing inner race all are provided with certain tapering, so this device has the rotating accuracy that the self-aligning function also can guarantee bearing.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the I portion enlarged diagram of Fig. 1.
Number in the figure: 1 is axle, and 2 is bearing inner race, and 3 is rolling element, and 4 is bearing outer ring, and 5 is bearing support, and 6 is the bearing setting sleeve.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated:
As shown in Figure 1, present embodiment comprises: axle 1, bearing inner race 2, rolling element 3, bearing outer ring 4, bearing support 5, bearing setting sleeve 6.Wherein: bearing inner race 2 cooperates with axle 1, and bearing setting sleeve 6 cooperates with bearing outer ring 4, and bearing setting sleeve 6 is by being bolted on the bearing support 5.Specification, model and the material of bearing inner race 2, rolling element 3, bearing outer ring 4, bearing setting sleeve 6 should be determined with designing requirement according to actual needs.Two row rolling elements 3 are covered with raceway, and retainer is not set, and according to concrete usage requirement, rolling element 3 both can adopt cylindrical body, also can adopt spheroid.
As shown in Figure 2, the inwall of bearing inner race 2 is provided with the tapering of 1:12, the outer wall of bearing setting sleeve 6 is provided with the tapering of 1:50, after the package unit assembling is finished, bearing setting sleeve 6 closely cooperates with bearing support 5, bearing inner race 2 closely cooperates with axle 1 simultaneously, thereby has eliminated the axial and radial clearance of bearing, has reached to reduce to vibrate, reduce noise, raising bearing running accuracy and the purpose in working life.The end of bearing setting sleeve 4 is provided with bolt hole, is used for fixing with bearing support.
